The structures of products A and B formed in the Edman degradation of dipeptide are- 
(a)
B = 
B = (b)
B = 
B = (c)A = 
B = 
B = (d)A = 
B = 
B = Answer
Answer (as printed): D
Explanation
The mechanism of the reaction is shown below: Edman degradation method is used for N-terminal analysis of protein. Since this method can label and cleave the peptide from N-terminal and forms corresponding and forms corresponding phenylthiohydonation derivative of amino acid.
